    摘要: An accommodating intraocular lens (40) is provided that having optical parameters that are altered in-situ using forces applied by the ciliary muscles, in which a lens body carries an actuator (42) separating two fluid-filled chambers (57,62) having either the same index of diffraction or different indices of refraction, actuation of the actuator changing the relative volumes of fluid (59,65) within an optic element of the lens and altering the optical power of the lens.

    摘要: An accommodating intraocular lens includes an optic portion, a haptic portion. The optic portion of the lens includes an actuator that deflects a lens element to alter the optical power of the lens responsive to forces applied to the haptic portion of the lens by contraction of the ciliary muscles and a secondary deflection mechanism. Movement of the lens element by the actuator causes the lens element to deform and the secondary deflection mechanism causes the lens to further deform.
